enter image description here I have a model and want to shrink or press or bend on red axis show in the image to make the shape as shown in reference image. I cant add loop cut & if i add sub division modifier i loose all the sharpness of the edges. U can try with my model i have attach the file.....

Added lattice and modified little bit to get the shape

enter image description here

confused problem enter image description here

with the reference video i have yet to errorenter image description here

    $\begingroup$ Loop cuts work only on connected faces made of quads, Polygons with less or more than 4 vertices will break the loop, as well as unconnected or duplicated vertices. $\endgroup$

press Shift+A and add a lattice lattice after that, select the object to be deformed and add a lattice modifier latticemodifier Under the modifier, make sure you select the lattice as the object lattice_object select your lattice, and go to edit mode, pressing TAB key; press Shift+leftclick to select the 4 vertices on the -Y direction of the lattice, press S to scale them.deforming_lattice I've uploaded your blend file with the lattice:

  • $\begingroup$ Im little bit confuse with my file or with the method plz i want to confirm as i do not want mean time my problem to be solve i like life time problem to be solve when ever i use it should work same way and with perfection. As in the image i have taken the lattice and add 3x3 cut and then i click on my model and add the lattice modifier. going into the edit mode as i see that the corner when stretch it works but with the center it did not work. Sorry for repeating the question again. What im doing is the correct way or can u plz explain whats the correct and where im going wrong $\endgroup$

  • $\begingroup$ instead of 3x3, try 4x4 and scale the middle group of vertices. Do a lattice form like this one: youtube.com/watch?v=-NbzlQVmloE $\endgroup$

    $\begingroup$ i got the solution i subdivide the model 2 times and then add the lattice modifier and got the shape. Thanks $\endgroup$

You dont have a pure quad mesh. Loop cuts will only work with a mesh that the faces are 4 sided, and what you have is a n-gon mesh (sometimes 3 sides, sometimes 5 sides, or even more) - you have to remesh to a pure quad mesh, consider retopology techniques using mainly squares or rectangles to build the mesh. Another problem is your normals, that are not consistent: while in Edit mode, select all, press space write "consistent" and select "make normals consistent"; or recalculate the normals. In case you don't want to do retopology, you can add curve objects and use modifier deform by curves, or even add a lattice object and deform your "steel object" by it, using lattice modifier.

  • $\begingroup$ Yeah ur right i don't want to do again. lattice is not working i tried it. can u tell me modifier deform by curves how it works i never used it $\endgroup$

  • $\begingroup$ well, I just performed the lattice modifier to your object and it worked. I'll add another answer explaining how to. wait a bit $\endgroup$

  • $\begingroup$ Well done! Next time, you want to model something like this, remember the quad rule! The tricky parts will be when you want to perform boolean modifiers, like the circles you carved! you have to match the number of vertices to neighbour number of vertices, to keep quadrangle faces. Please look for tutorials on retopoly faces, and see how they manage around the eyes. $\endgroup$

  • $\begingroup$ other thing, when you apply subdivision surfaces and you want to get some sharp edges, select the edges you want to be sharp, press N (for right lateral menu), under "transform", increase the "crease" value to 1, and that edge will be sharper than the others. $\endgroup$
